英文摘要: Synthesis, characterization and thermal analysis of polyaniline (PANI)/ZrO2 composite and PANI was reported in our early work. In this present, the kinetic analysis of decomposition process for these two materials was performed under non-isothermal conditions. The activation energies were calculated through Friedman and Ozawa-Flynn-Wall methods, and the possible kinetic model functions have been estimated through the multiple linear regression method. The results show that the kinetic models for the decomposition process of PANI/ZrO2 composite and PANI are all D-3, and the corresponding function is f(alpha)=1.5(1-alpha)(2/3)[1-(1-alpha)(1/3)]-1. The correlated kinetic parameters are E-a=112.7 +/- 9.2 kJ mol(-1), InA=13.9 and E-a=81.8 +/- 5.6 U mol(-1), InA=8.8 for PANI/ZrO2 composite and PANI, respectively.
